Werth is about as good a leadoff choice as we have right now.
He's always ground at bats out and he has a really solid OBP generally. Batting leadoff lets him focus on just making contact, not having to drive the ball. I think this is the best way anyway for a player coming back from injury to get the timing down, so it's a win - win.
THank God somebody got to Matt about batting Taylor #1.
